A Virtual Reality Intervention to Reduce Dementia-Related Agitation Using Single-Case Design.

Objectives: The primary objective of this study was to use a single-case design to evaluate the utility of a VR intervention to reduce agitation behaviors in two female participants with a diagnosis of dementia.

Methods: A single-case research design with an ideographic approach was selected given the novelty of this intervention. A blended single case experimental design was used combining the Multiple-baseline design across individuals with a reversal design to examine the effects of VR nature scenes on agitation. Visual analysis was used to determine changes in mean, level, and latency of the behaviors.

Results: For both participants, a significant decrease in their respective agitation behaviors was observed during intervention phases.

Conclusions: This study provides preliminary evidence of the utility of VR as a brief and effective intervention to decrease agitation in individuals with dementia.

Clinical Implications: These initial, promising results may help caregivers improve the quality of life for dementia patients. Further, the brevity of the intervention makes this a practical tool for care providers working in clinical settings. The primary objective of this study was to use a single-case design to evaluate the utility of a VR intervention to reduce agitation behaviors in two female participants with a diagnosis of dementia.
